Coverage, Capacity, and Connectivity
Coverage area
The AprilAire 80-Pint Whole-House Dehumidifier handles spaces up to 4,400 square feet. This makes it suitable for larger basements or entire homes where humidity control is needed across a broad footprint. In contrast, the AprilAire 70-Pint Wi-Fi Crawl Space Dehumidifier is rated for up to 2,200 square feet. If you have a smaller basement or a dedicated crawl space, the 70-pint model covers that range adequately. For larger areas, the 80-pint unit provides the necessary margin to maintain consistent humidity levels without running continuously. Choose the larger coverage model if your space exceeds 2,200 square feet.
Moisture removal
Capacity is measured in pints per day (PPD). The AprilAire 80-Pint Whole-House Dehumidifier removes up to 80 pints of moisture daily. This higher capacity helps manage heavy dampness in large or very humid environments more efficiently. The AprilAire 70-Pint Wi-Fi Crawl Space Dehumidifier removes 70 pints per day. While slightly lower, this is sufficient for many standard crawl spaces and smaller basements. If you experience persistent dampness or have a larger volume of air to process, the 80-pint model offers faster moisture extraction. For moderate humidity levels in a smaller area, the 70-pint capacity is often adequate.
Smart connectivity
Remote control and monitoring capabilities differ significantly between these two models. The AprilAire 70-Pint Wi-Fi Crawl Space Dehumidifier features built-in Wi-Fi and Bluetooth. You can pair it with the Healthy Air App to monitor and control the unit from your phone. It sends alerts and diagnostics directly to your device. The AprilAire 80-Pint Whole-House Dehumidifier data does not list built-in Wi-Fi or app connectivity as a standard feature for the base model. While variations exist, the core 80-pint unit relies on local control. If you want remote monitoring from anywhere, the 70-pint Wi-Fi model is the clear choice.
Physical dimensions
Size matters for placement in tight crawl spaces or closets. The AprilAire 70-Pint Wi-Fi Crawl Space Dehumidifier is compact, measuring 12.5 inches wide, 12.5 inches deep, and 12.5 inches high. It weighs 56 pounds. This square footprint makes it easy to fit into confined areas. The AprilAire 80-Pint Whole-House Dehumidifier is larger, measuring 15.4 inches wide, 34 inches long, and 17.1 inches high, weighing 63 pounds. Its elongated shape requires more linear space. If you have limited clearance or need to fit the unit into a tight corner, the 70-pint model’s compact design offers a practical advantage.
Drainage method
Both units are designed for continuous operation without manual water emptying. They both support drainage via a hose connection. You can place either unit over a floor drain or connect a hose to route water away. The AprilAire 70-Pint Wi-Fi Crawl Space Dehumidifier also mentions compatibility with ducting and hanging kits for off-floor installation. The AprilAire 80-Pint Whole-House Dehumidifier emphasizes its drain hose setup for basements. Neither model lists a removable water tank for manual emptying in their key specs. For both, you will need to plan for a drain line or floor drain location near the unit.
